Kuroutoshikou Galakuro Gaming GeForce RTX 5070 Dual Fan OC

Manufacturer: Kuroutoshikou

The Kuroutoshikou Galakuro Gaming GeForce RTX 5070 Dual Fan OC is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process and housing 31.1 billion transistors. It ships with 12GB of GDDR7 VRAM across a 192-bit memory bus, delivering an effective memory speed of 28,000 MHz and a peak bandwidth of 672 GB/s. The card runs at a base clock of 2,325 MHz with a boost up to 2,527 MHz, and includes RGB lighting along with support for up to four simultaneous displays.

On the feature side, the card supports DirectX 12 Ultimate and OpenGL 4.6, along with ray tracing, DLSS, and stereoscopic 3D. Its 6,144 shading units are complemented by 192 texture mapping units and 80 render output units, yielding a texture rate of 485.2 GTexels/s and a pixel rate of 202.2 GPixel/s. Connectivity is handled through one HDMI 2.1b port and three DisplayPort outputs, while the card connects to the system via PCIe 5.0. With a 250W TDP, dimensions of 240 mm × 115.5 mm, and a three-year warranty, it also supports Intel Resizable BAR and ECC memory.

Pros
  • Supports up to four simultaneous displays, offering flexibility for multi-monitor setups
  • Includes ray tracing and DLSS support, enabling more advanced rendering capabilities
  • ECC memory support adds a layer of data integrity useful for compute-oriented workloads
  • The three-year warranty provides solid long-term coverage
  • HDMI 2.1b and three DisplayPort outputs cover a wide range of modern display connectivity needs
  • RGB lighting is built in, giving users visual customization options without requiring additional hardware
Cons
  • The 192-bit memory bus width is narrower than what higher-tier cards in this category typically offer, which limits maximum memory bandwidth headroom
  • No USB-C video output is available, which may be restrictive for users with USB-C monitors
  • Water cooling is not supported, limiting thermal management options to air cooling only
  • With a 250W TDP, the card has a relatively high power draw that may require a capable power supply
Who is this for?

This card is well suited to users who engage in demanding rendering and compute workloads, given its 31.05 TFLOPS of floating-point performance, DPFP support, and ECC memory capability. Those running multi-monitor setups of up to four displays will find the combination of three DisplayPort outputs and one HDMI 2.1b port particularly practical. The inclusion of ray tracing, DLSS, and DirectX 12 Ultimate also makes it a solid fit for users who prioritize advanced real-time graphics features in their workflow or gaming sessions.

Who is this NOT for?

Users who require USB-C display connectivity will find this card lacking, as it offers no USB-C output whatsoever. Those working in thermally constrained or small form-factor builds may also struggle, since the card's 250W TDP and air-only cooling demand adequate case airflow and a capable power delivery setup. Additionally, users with workloads that benefit from a wider memory bus — such as certain high-resolution texture pipelines — may find the 192-bit bus width a limiting factor compared to what broader configurations can sustain.
